While marine pollution can be obvious, as with the marine debris shown above, it is often the pollutants that cannot be seen that cause most harm.. Marine pollution occurs when substances used or spread by humans, such as industrial, agricultural and residential waste, particles, noise, excess carbon dioxide or invasive organisms enter the ocean and cause harmful effects there.
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [3]
A garbage patch is a gyre of marine debris particles caused by the effects of ocean currents and increasing plastic pollution by human populations. These human-caused collections of plastic and other debris are responsible for ecosystem and environmental problems that affect marine life, contaminate oceans with toxic chemicals, and contribute ...
Research shows that marine plastic pollution has impacts on marine ecosystems and economic activities at various levels, [53] [54] but further studies are currently being conducted to thoroughly investigate the size of such impacts in the Mediterranean area, [2] both on marine biota and on human health.

In addition to human health, animal health is also seriously threatened by mercury pollution in the ocean. The effects of high mercury levels on animal health were revealed by the severe mercury poisoning in Minamata Bay in which many animals exhibited extremely strange behaviors and high mortality rates after consuming contaminated seafood or ...
Water pollution (or aquatic pollution) is the contamination of water bodies, with a negative impact on their uses. [ 1 ] : 6 It is usually a result of human activities. Water bodies include lakes , rivers , oceans , aquifers , reservoirs and groundwater .
Ballast water discharge typically contains a variety of biological materials, including plants, animals, viruses, and bacteria. These materials often include non-native, nuisance, and exotic species that can cause extensive ecological and economic damage to aquatic ecosystems, along with serious human health issues including death.
